Bosch Sensortec

Bosch Sensortec is the MEMS sensor arm of Bosch, and the profiles here span its two strongest lines: environmental sensing and motion tracking. The BME280 combines humidity, pressure and temperature measurement in a single package — the reference combo sensor behind countless weather stations, wearables and indoor-air-quality monitors — while the BMP280 covers barometric pressure and temperature for altitude tracking and weather applications. Both are digital-output parts with I2C and SPI interfaces and compact LGA footprints, and the choice between them turns on whether the design needs humidity data. The third profile is the BNO055 9-axis absolute orientation sensor with an integrated microcontroller running sensor fusion. Note the lifecycle reality: Bosch Sensortec lists the BNO055 as not recommended for new designs, so programs still shipping on it need a verified migration plan. Confirm the exact ordering code against the BOM, since package and interface variants are not interchangeable.

Sourcing notes for Bosch Sensortec parts. Always quote the complete manufacturer ordering code — package, temperature grade, speed or accuracy grade, and packing (reel, tube or tray) all change availability and price, and suffixes are where most mismatches happen. Check the lifecycle status on the manufacturer site before committing to a multi-year build; parts flagged not-recommended or obsolete need a last-time-buy plan or a verified alternate lined up early. With every offer, request traceability documents — date code, lot code and original packing — and confirm the inspection steps your supplier applies to high-risk lots.
